Fig. 1.

Results for 6 individual centres. Mean dosimetric variations between consecutive image sets are shown. Error bars indicate SD, median values are shown as horizontal bars. Open symbols correspond to the intra-application group, filled symbols to the inter-application group. ^∗3 extreme outliers $\mathrm{\Delta }{D}_{2{\text{cm}}^3}=119-240\%$ were excluded from the analysis shown in this graph. Inclusion would result in 20.5 ± 54.5% (mean ± SD) for rectum for MVCC, as compared to 0.6 ± 17.4% without outliers.
